4.5 Recessing cy
cles
Recessing, radial—expanded
Call the recessing cycles
Select recessing, radial
Press the Expanded soft key
The cycle machines the number of recesses defined in number Qn. The
parameters for the contour starting point and contour end point
define the first recess (position, recess depth and recess width).
Cycle parameters
X, Z
Starting point
X1, Z1 Contour starting point
X2, Z2 Contour end point
B1, B2 Chamfer/rounding arc (B1 contour start; B2 contour end)
 B>0: Radius of rounding
 B<0: Width of chamfer
A Start angle (range: 0° <= A < 90°)
W End angle (range: 0° <= W < 90°)
R Rounding arc
I, K Oversize X, Z
G14 Tool change point (siehe Seite 140)
T Turret pocket number
ID Tool ID number
S Spindle speed/cutting speed
F Feed per revolution
P Recessing width: Infeeds <= P (no input: P = 0.8 * cutting
width of the tool)
ET Recessing depth by which one cut is fed.
EZ Dwell time for chip breaking (default: length of time for
two revolutions)
Qn Number of recess cycles (default: 1)
DX, DZ Distance to subsequent recess with respect to the
preceding recess
G47 Safety clearance (siehe Seite 140)
